Alzheimer’s disease (AD) is recognized worldwide for its debilitating symptoms of declining cognitive function and gradual memory loss. What remains less clear is exactly what causes the neurodegenerative disease, and how to treat it. “Alzheimer’s disease is characterized by two key pathologies – beta-amyloid plaques and tau neurofibrillary tangles.” Seung-Yong Yoon, CEO of Adel Inc., told BioWorld. “Adel is looking to develop a tau-targeting drug, considering tau has been more correlated with AD symptom progression, and the industry’s need for tau pipelines.”
